Description
Technical field
The utility model relates to detector field, particularly relates to a kind of Infrared Detectors.
Background technology
In recent years, developing rapidly of China's Aero-Space cause, industrial and agricultural production and science and technology, Infrared Detectors technology is got more and more in different field, is increasingly widely applied.Due to Infrared Detectors except volume itself is little, lightweight, the advantages such as black light can be identified in addition to, the most also there is high detectivity, substantially wavelength is not limited, can normally use under room temperature and reliable structure, there is the advantages such as preferable stability, therefore, had in fields such as aerospace field, national defense construction, industrial and agricultural production, communications and transportation and scientific research systems and be widely applied.
Owing to Fresnel Lenses machine-shaping is convenient, cheap the most many Infrared Detectors all use Fresnel Lenses as optical filter, but the most common Fresnel Lenses Infrared Detectors investigative range is narrower, part Infrared Detectors is installed more complicated, can not carry out single component replacing, later maintenance cost is higher.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and direct, practical Infrared Detectors, to reach to expand investigative range, improves detection accuracy, and single component is changed simple, reduces later maintenance cost.
nullFor realizing the purpose of this utility model，Offer techniques below scheme: a kind of Infrared Detectors，Including optical filter、Sensor-based system、Circuits System、Display system、Power-supply system and encapsulating housing，Described optical filter is fixed on filter and fixes and be positioned at encapsulating housing front end on seat，Described sensor-based system is fixed on the fixing seat of sensing and is positioned in the middle part of encapsulating housing，Described display system is fixed on the fixing seat of display and is positioned at encapsulating housing rear portion、Described Circuits System is connected with sensor-based system and display system，Between sensor-based system and display system，Described display system includes that display screen drives plate and display screen，Described power-supply system is positioned at below display system，Described optical filter includes Fresnel Lenses and parabolic mirror，Described optical filter includes Fresnel Lenses and parabolic mirror，Described Fresnel Lenses is the multilayer multiple viewports Fresnel Lenses that toroidal Fresnel Lenses cuts into that the regular arrangement of sheet forms，The number of plies is 1-5 layer.
Including that heat releases sensing chip and semiconductor cooler as preferred described sensor-based system, described heat releases the pyroelectricity sensitivity unit that sensing chip includes that two electrodes in series or in parallel with each other are contrary, and heat is released sensing chip and is connected with Circuits System by signal leading-out terminal.
Having shielding plate as preferred described optical filter front end, shielding plate upper end is provided with blocks motor.
Fix seat, the fixing seat of sensing as preferred described filter, show that fixing seat is all connected with encapsulating housing by screw.
Described Circuits System is prior art, generally comprises amplifier, bigoted resistance and FET.
The beneficial effects of the utility model: the multilayer multiple viewports Fresnel Lenses that toroidal Fresnel Lenses cuts into the regular arrangement of sheet and forms can expand investigative range, parabolic mirror makes focusing more accurate, each assembly is connected with encapsulating housing by respective fixing seat makes installation, dismounting simpler, later maintenance only need to change the assembly of damage, reduces maintenance cost.
